You can never have enough lead sounds, so here's a versatile program, with which you can create Minimoog-style monophonic leads (or sustained basses) in seconds, using just the sliders.

The program is based around the standard subtractive structure, 2 oscillators into a filter with envelope, into the amp with envelope, and a LFO for vibrato. I included 4 variations of the program, which differ in the waveform of the second oscillator or have additional processing between the oscillators and the filter. Effects are a limited but effective choice of chorus on/off and clocked delay with one slider for both delay level and time.

MiniMock Saw 1 - Classic lead with two very lightly detuned sawtooth waves. Slider B raises the pitch of oscillator 2 a fifthMiniMock Saw 2 - Variation of above, just using different slider/switch positions, which turns it into a resonant bass droneMiniMock Saw+Sqr - Classical lead with a mix of sawtooth and square wave. Slider B adjusts the balance between oscillator 1 and 2MiniMock Saw+PW - Thin lead with a mix of sawtooth and pulse wave. Slider B adjusts the pulsewidth of oscillator 2MiniMock Saw+Shp - Inserts a shaper between the two sawtooth oscillators and the filter. Slider B adjusts the shaper amountMiniMock Saw+Dst - Inserts a distortion block between the two sawtooth oscillators and the filter. Slider B adjusts the distortion level

...would be great if you are able to recreate something close to wonderful solo's sounds coming from Minimoog or Moog Source of the great Toby Smith from Jamiroquai (Space cowboy and so on...that liquid and intense sound he uses a lot in that fantastic band)

Hmm, I have to admit that I haven't listened to Jamiroquai since my student days in the nineties. Wikipedia says there are two different versions of Space Cowboy. Which one are you after? I suggest you post a request with a link to a video and exact time index in the Sound Requests forum.
